Product details
Overview
MPLAD36KP160CAE3 from Microsemi is a bidirectional surface-mount transient voltage suppressor (TVS) designed for high-energy surge protection in aerospace and automotive power systems. It delivers 36,000 W peak pulse power at 10/1000 μs, features a 160 V reverse standoff voltage (VWM), clamps to ≤259 V at 10 A IPP, and operates across –55°C to +150°C junction temperature. It is qualified to AEC-Q101 and meets RTCA DO-160 Section 22 multi-stroke lightning requirements.
For engineers reviewing the MPLAD36KP160CAE3 datasheet, MPLAD36KP160CAE3 pinout, MPLAD36KP160CAE3 application, or MPLAD36KP160CAE3 equivalent, key selection criteria include its bidirectional polarity, 1.0°C/W junction-to-case thermal resistance, IEC 61000-4-5 Class 5 secondary lightning protection (42 Ω source), RTCA/DO-160F Waveform 4 Level 4 compliance, and RoHS-compliant e3 termination plating.
Technical Context
This TVS diode uses an avalanche breakdown mechanism to clamp transients with sub-5 ns response time in bidirectional configuration. Its void-free UL94V-0 epoxy package and metal-base cathode construction enable low thermal resistance (RθJC = 1.0°C/W) and efficient heat dissipation into PCB copper pads.
It is characterized for 10/1000 μs impulse waveforms per IEC 61000-4-5 and RTCA/DO-160F Waveform 4 (6.4/69 μs) and Waveform 5A (40/120 μs), with derated PPP above 100°C case temperature per Figure 3. Standby current ID is ≤10 μA at VWM = 160 V, and temperature coefficient αV(BR) is +195 mV/°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPP) | 36,000 W @ 10/1000 μs - enables single-device protection against severe lightning-induced surges in avionics bus lines |
| Reverse Standoff Voltage (VWM) | 160 V - sets maximum continuous operating voltage before clamping initiates; matches 115 VAC-derived DC rails with safety margin |
| Clamping Voltage (VC) | 259 V @ IPP = 10 A - defines worst-case voltage seen by downstream circuitry during surge event |
| Junction-to-Case Thermal Resistance | 1.0 °C/W - allows direct thermal coupling to heatsink or large copper pour for sustained multi-pulse operation |
| Standby Current (ID) | ≤10 μA @ 160 V - ensures negligible leakage in always-on power monitoring or sensor circuits |
| Operating Temperature Range | –55°C to +150°C - supports deployment in engine bay, flight control, or industrial motor drive environments |
| RoHS Compliance | e3 marking - matte-tin plating compliant with EU RoHS Directive 2011/65/EU, no lead or hazardous substances |

Use Scenario: Hardening 75 Ω RS-485 communication ports in trackside signaling controllers against induced surges from nearby traction currents. IC Role / Device Role / Timing Role: Line-side TVS on differential data pairs, configured bidirectionally to handle ±1 kV common-mode transients. Use Value: 160 V VWM avoids false triggering during normal 12 V bias swing while clamping 42 Ω IEC 61000-4-5 Class 4 surges to safe levels. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160CA | Lower PPP (600 W), SMA package, RθJC = 40°C/W | Not suitable for DO-160 multi-stroke or IEC 61000-4-5 Class 5; limited to consumer-grade surge zones | Select only for cost-sensitive, low-energy applications where thermal budget and certification are not required |
| SMCJ160CA | PPP = 1500 W, SMC package, RθJC = 15°C/W, same VWM/VC | Lacks AEC-Q101 and DO-160 qualification; insufficient for aviation or high-reliability automotive use | Use where moderate surge immunity suffices and full qualification documentation is unnecessary |
Compared with SMBJ160CA and SMCJ160CA, the MPLAD36KP160CAE3 provides 24× and 24× higher peak pulse power respectively, certified thermal performance (RθJC = 1.0°C/W), and formal qualification to RTCA DO-160F and AEC-Q101 - making it the sole option for certified aerospace and mission-critical automotive deployments.

FAQ
What is the clamping voltage of the MPLAD36KP160CAE3 at its rated peak pulse current?
The MPLAD36KP160CAE3 has a maximum clamping voltage (VC) of 259 V at 10 A peak pulse current (IPP) under 10/1000 μs waveform conditions. This value is measured per Figure 3 in the RF01216 datasheet and defines the upper voltage limit imposed on protected circuitry during surge events. The MPLAD36KP160CAE3 maintains this clamping performance across its full operating temperature range when mounted per recommended pad layout.
Is the MPLAD36KP160CAE3 qualified for automotive applications?
Yes, the MPLAD36KP160CAE3 is fully qualified to AEC-Q101 for stress testing including temperature cycling, mechanical shock, and humidity exposure. It is explicitly rated for automotive load dump protection and appears in Microsemi's documentation as suitable for engine control modules and battery management systems. The MPLAD36KP160CAE3 also carries wafer and assembly lot traceability for high-reliability automotive deployment.
Does the MPLAD36KP160CAE3 meet RTCA DO-160 lightning standards?
Yes, the MPLAD36KP160CAE3 is validated for RTCA DO-160F Section 22 multi-stroke lightning testing at Level 4 (Waveform 4, 6.4/69 μs) and Level 5 (short-distance configuration). Its 36 kW rating and low thermal resistance enable reliable performance across repeated strikes - a requirement for aircraft power distribution units and flight control electronics. The MPLAD36KP160CAE3 is referenced directly in the RF01216 datasheet for DO-160 compliance.
What does the "CA" suffix indicate in MPLAD36KP160CAE3?
The "CA" suffix in MPLAD36KP160CAE3 denotes bidirectional polarity - meaning the device provides symmetrical clamping for both positive and negative transients. This distinguishes it from unidirectional variants (e.g., MPLAD36KP160AE3) and enables use in AC-coupled or floating signal paths. The MPLAD36KP160CAE3's bidirectional behavior is confirmed in the "Polarity" section of the RF01216 datasheet and reflected in its dual-breakdown characteristic.
What is the thermal resistance specification for the MPLAD36KP160CAE3?
The MPLAD36KP160CAE3 has a junction-to-case thermal resistance (RθJC) of 1.0°C/W, measured with case temperature controlled on a heatsink as specified in the datasheet. This ultra-low value results from its metal-base cathode construction and optimized epoxy molding, enabling efficient heat transfer to PCB copper or external heatsinks. For thermal design, the MPLAD36KP160CAE3 requires a minimum 100 mm² copper pad area per the recommended pad layout in RF01216.
